Is CAAM by default enable?

Hi,

I am new to imx processor.I am working on imx7d sabresd board, and I am using linux-4.1.15 .Right now I am exploring Hardware Acceleration in CAAM. I refer many article and I also test by loading cryptodev.ko module and then openssl command(link :Cryptography Users Guide - Texas Instruments Wiki ). I am getting difference in CPU usage.

That is fine. But my question is , When hardware acceleration is used by processor?, Like by default when we connect over network at that time, or we need to set anything for that? or only if we insert cryptodev module then only it is used hardware acceleration?

Kindly clear my doubt.

Thanks in advance.

Hello,

You may be needed to install CAAM driver / module. The CAAM drivers are accelerated through

the CryptoDev interface.

# modprobe cryptodev

Yuri.
